The venue was confirmed at a media conference this morning.
The New Zealand boxer is set to face the Mexican-American Ruiz on 10 December.
Duco chief executive Martin Snedden said it had been a "rocky, volatile" few weeks, as he confirmed the Auckland venue.
But he said it was now time to enjoy the build-up to next month's bout.
"This will capture people in Auckland and New Zealand Joseph has become a figure new Zealanders have really warmed to."
